I agree.  I suggest eliminating self moderated threads in the currency trading section for a start.  At least don't let noobs do it.

This is what I warned would happen when saudibull got caught, he'd just come back again and this time he'd start using self-moderated posts from day one.  Which he has under this new name of LP.

All we can do is yell to the mods until they change something.  I agree this system is f'd. 

How about a permanent cookie in their browser admins?  LP isn't that smart, he'd never see it.  You could use it to DETERMINE he is one and the same scammer.  How about a permanent block on his IP and subnet?
